Ontario Reports Third Blood Clot Associated With AstraZeneca Coronavirus Vaccine
Ontario health officials are reporting a third case of a rare blood clot associated with AstraZeneca’s COVID-19 vaccine.
Ontario’s Chief Medical Officer of Health Dr David Williams said Monday that a man in his 60s is the last person to suffer from a clot after receiving a dose of the vaccine. The man is currently being treated in hospital.
The province last week reported its first two cases of the disease, known as vaccine-induced immune thrombotic thrombocytopenia (VITT).
One was with a man in his 60s who was recovering at home after receiving treatment. The other person’s family – a Hamilton man in his 60s – told CTV News he is now fighting for his life in hospital after suffering a severe stroke associated with the clot.
Ontario has now distributed about 650,000 doses of the AstraZeneca vaccine, and Williams said the chances of an extreme adverse reaction remain low.
“So we continue to monitor the situation, we continue to document them, investigate them, and in partnership with our federal, provincial and territorial teams, we are looking at them nationally,” Williams said at a conference. hurry. conference Monday.
He noted that while there is a low risk associated with the AstraZeneca vaccine, it is very low “compared to other similar drugs and very low compared to getting COVID and complications from COVID.”
“So we always want to encourage everyone, when it’s your turn or your opportunity to get the vaccine, to get the vaccine,” Williams said.
He added that the province is already starting to see the benefits of vaccination among its older population, who have been on the front lines for doses.
“We are seeing many strong indications of the benefits of vaccination, as our case rates in older population groups – those over 60, certainly over 80 – and our death rates have declined, as well. than our hospitalization rates in these ages. groups go down, ”Williams said. “So this shows you that the vaccine is working. “
Last week, the province lowered the age threshold to 40 for those who want to get a dose of AstraZeneca through a pharmacy or doctor’s office. The National Advisory Committee on Immunization (NACI) also lowered its own recommendation to those 30 and older, but Ontario said it would not lower the age restriction further until it there is no more supply available.
Some 4.1 million doses of the vaccine are expected to arrive in Canada from various sources by the end of June. There are reports that the United States may soon allow part of its stocks to leave the country. The United States is said to have tens of millions of doses of AstraZeneca in storage or in various stages of production under a contract with the company, but has so far refused to let most of those doses leave the country.
